1st code:

import java.util.ArrayList;

import java.util.List;

public class Node {

public int value;

public List children;

public Node(int value) {

this.value = value;

this.children = new ArrayList();

}

public List getParents(Node root, int valueToSearch) {

List path = new ArrayList();

if (root == null) {

return path;

}

if (root.value == valueToSearch) {

path.add(root);

return path;

}

for (Node child : root.children) {

List childPath = getParents(child, valueToSearch);

if (!childPath.isEmpty()) {

path.add(root);

path.addAll(childPath);

return path;

}

}

return path;

}

}

2nd code:

import java.util.List;

import java.util.ArrayList;

public class Triangle {

public static List maxPerimeterTriangle(List lines) {

int max_perimeter = 0;

List max_triangle = new ArrayList<>();

for (int i = 0; i < lines.size(); i++) {

for (int j = i + 1; j < lines.size(); j++) {

for (int k = j + 1; k < lines.size(); k++) {

int a = lines.get(i), b = lines.get(j), c = lines.get(k);

if (a + b > c && a + c > b && b + c > a) {

int perimeter = a + b + c;

if (perimeter > max_perimeter) {

max_perimeter = perimeter;

max_triangle = List.of(a, b, c);

}

}

}

}

}

return max_triangle;

}

}

can you please make this codes executable in an online compiler without errors because I posted a question here specifically stating " please include an Online link to see and to run the codes on an online compiler site which has no access problems."

even if there was no link, I wanted the code runnable at least, but it gave me this error: "class Triangle is public, should be declared in a file named Triangle.java" and a similar one for the first code but even thought I tried searching "how to execute it in an online complier" and tried writing the call function it still wasn't running and even giving me more errors sometimes, I couldn't figure it out for both codes so please help and thank you in advance
